Implicit:

By eliminating unnecessary casts, implicit conversions can
improve source code readability. However, because implicit
conversions can occur without the programmer's specifying
them, care must be taken to prevent unpleasant surprises.
In general, implicit conversion operators should never
throw exceptions and never lose information so that they
can be used safely without the programmer's awareness. If a
conversion operator cannot meet those criteria, it should
be marked explicit.

class MyType
{
public static implicit operator int(MyType m)
{
// code to convert from MyType to int
}
}

MyType x;
// implicitly call MyType's MyType-to-int conversion
operator
int i = x;

Explicit:
declares a user-defined type conversion operator that must
be invoked with a cast. For example, this operator converts
from a class called Fahrenheit to a class called Celsius:

// Must be defined inside a class called Farenheit:
public static explicit operator Celsius(Farenheit f)
{
return new Celsius((5.0f/9.0f)*(f.degrees-32));
}

Farenheit f = new Farenheit(100.0f);
Celsius c = (Celsius)f;
